About MDRNA, Inc.

MDRNA is a biotechnology company focused on the development and commercialization of therapeutic products based on RNA interference (RNAi). Our goal is to improve human health by combining novel RNAi-based compounds and proprietary peptide- and liposomal-based drug delivery technologies to provide superior therapeutic options. Our multi-disciplinary portfolio of capabilities includes molecular biology, cellular biology, formulation expertise, peptide and alkylated amino acid chemistry, pharmacology, toxicology and bioinformatics. We are applying this expertise to a single, integrated drug discovery platform that will be the engine for our clinical pipeline and a versatile platform for establishing broad therapeutic partnerships. We are also building on new technologies, such as UsiRNAs that incorporate the non-nucleotide moiety Unlocked Nucleobase Analog (UNA) within the siRNA molecule, that we expect to lead to safer and more effective RNAi-based therapeutics. By combining broad expertise in siRNA science with proven delivery platforms and a strong and growing IP position, MDRNA is well positioned as a leading RNAi therapeutics company and value-added collaborator for our research partners.
